To add multiple pictures to a media gallery:

  1. Press the plus icon in the bottom right corner.
  2. Press Create Post. 
  3. Take/Choose up to 3 pictures (up to 10 on TONIT Full Throttle) from your device.
  4. Crop each picture individually by pressing the cropping icon in the top left of each picture.
  5. Swipe to the left/right to browse through your gallery.
  6. Add text/location and press the blue checkmark to upload your content.

A counter in the top right of each image as well as the blue dots below the gallery will indicate what picture you're on.

Tip: If you want to keep the aspect ratio of your picture, try uploading only 1 picture and leave it uncropped. The picture will then post with a maximum aspect ratio of 3:4.
